I think slightly better would be
const strunct serdev_device *
serdev_match_id(const struct serdev_device_id *id,
const struct serdev_device *sdev)

Can we avoid ping-pong changes in the series? I mean to introduce this
helper in this form in the first place?

return !!serdev_match_id(...);
?

Same as above.
